A collection of some of the neat math and physics tricks that I've collected over the last few years.

Toy Gaussian Splatting visualization in Unity

Unity Inverse Kinematics made easy

Unity sample of 3D pose estimation

Simple and fast IK solver for Unity

PLY (Polygon File Format) importer for Unity

IK Solver using Cyclic Coordinate Descent on Unity

Use of forward and inverse kinematics using CCD and Jacobian methods. Oriented for people willing to learn IK theory.
